IQ 90 to 109
Average
The middle half of everyone. This band is wider than the others on purpose: the scale is built so that scores cluster densely around 100, which means small differences here move the percentile a lot and mean very little. A 98 and a 104 are, for practical purposes, the same score.
Every score from 90 to 109
Percentile is the share of people you would score above. Rarity is how many people it takes to find one at that score or higher. Scores with their own page are linked.

What scores in this range mean
A 100 is an ordinary score in the truest sense — it describes the reasoning ability of a large share of the population. Almost every job, degree and skill is held by people in this band, because it is where most people are.
Worth knowing: 100 is the exact midpoint of the scale, by construction.
One honest caveat that applies at every score: IQ measures a specific slice of reasoning ability. It is a real and useful signal, but it does not capture creativity, discipline, emotional intelligence, or drive. Treat it as one data point, not a verdict.
